Relief is a kind of sculpture. The sculptor carves the image he wants to shape on a flat plate, making it separate from the plane of the original material. Relief is the product of the combination of sculpture and painting. It deals with objects in a compressed way, and displays three-dimensional space by perspective and other factors. It is only for one side or two sides to see. The reliefs are usually attached to another plane, so they are used more in architecture and can be seen on utensils and implements. Due to its compression characteristics, it occupies less space, so it is suitable for decoration in a variety of environments. In recent years, it has played an increasingly important role in urban beautification. The relief is as rich and colorful as the round sculpture in content, form and material. The materials of relief include stone, wood, ivory and metal. The relief is a semi vertical sculpture whose image shape protrudes from the stone surface (as opposed to the relief). According to the different depth of stone removal in image modeling, it can be divided into low relief and high relief. The bas reliefs are single level statues with relatively simple contents; The high relief is a multi-level statue with complicated contents. The carving technique and expression style of relief are basically the same as those of round sculpture. Many ancient and modern large-scale memorial buildings, high-end mansions and private houses are equipped with such decorations. Their main works are wall blocks, flower windows, dragon columns (early) and column bases.

The tasks of decoration design are: first, to achieve the use function of the building itself, reasonably improve the material level of the indoor environment, so that people can be satisfied mentally, and improve the quality of the physical and psychological environment of the indoor space.

It should also follow the aesthetic principles to create a personalized and beautiful indoor environment, which fully reflects the spiritual connotation of different functional spaces and use objects. A designer can make interior design comfortable, scientific and artistic only if he has rich knowledge, high artistic accomplishment and the ability to solve practical problems.

The types of stone inscription monuments include monuments, memorial monuments, merit monuments, temple monuments, Dianzi monuments, mausoleum monuments, etc. Except for a few wordless steles, they are generally literal steles. Usually, characters are carved on the body of the stele, and some are accompanied by carved patterns. The pedestal and cover of the stele are mostly carved with decorations, birds, animals, flowers, and mascots. The cover of the stele of the imperial family is also carved with dragons and phoenixes.

Stone books are written with stone instead of paper, and carved instead of pen, which is very ingenious. There are many famous works of stone tablet processing and stone calligraphy carving. For example, "Xi'an Forest of Steles" includes more than 3000 historical steles from Han Dynasty to Qing Dynasty. It is the largest collection of stone books in China. Together with the "Forest of Steles in Hanlin" under construction in Kaifeng, it can be said that it is a sea of steles, and it is a collection of calligraphies of regular script, line, grass, seal script, clerical script and Wei style by famous calligraphers of all ages. In addition to large-scale carvings such as stele books and cliff carvings, there are also some stone carvings, such as mourning volumes in imperial tombs and modern fine carved small stone books, such as more than 100 mourning volumes of white marble excavated in the tomb of the prince of the Tang Dynasty, and six stone books of "Thirty six Strategies" carved in tile slate in modern Chengdu, a total of 26 pages and 1278 words, bound into a volume with eyeliner, each page is 2.2.6mm, which can be read.

Exterior wall decorative panel is a new type of integrated material for building exterior wall decoration and insulation developed in recent years, which is composed of polyester baking paint or fluorocarbon paint, carved aluminum zinc alloy steel plate, polyurethane insulation layer and glass fiber cloth; Beijing Abstract sculpture It is mainly used for exterior wall decoration and energy-saving reconstruction of gymnasiums, libraries, school and hospital office buildings, villas and other buildings; The main functions are building decoration, heat preservation, energy conservation, heat insulation, sound insulation, waterproof and mildew proof. The metal surface decorative insulation board is a large-area external hanging wall board produced industrially. It has good durability and low maintenance cost due to dry installation and construction. It integrates the functions of external wall insulation and decoration, and meets the requirements of high quality Abstract sculpture The development direction of building energy conservation "modularization" technology is an advanced technology vigorously promoted in the field of building wall external insulation technology in China.

European style components, also known as GRC European style decorative components. GRC is the abbreviation of Glass Fiber Reinforced Cement. Hainan GRC component is a composite material invented and widely used abroad in the 1970s. It is a new composite material made of fast hardening Portland cement and alkali resistant glass fiber mixed with appropriate additives. It combines light weight, high strength, high toughness, water resistance, incombustibility, sound insulation, heat insulation, easy processing and other characteristics. Hainan EPS has a unique position in building materials. It is mainly used to make interior and exterior decoration components of European style buildings to meet the needs of European style decoration.
